System-specific server memory kit

This NEMIX RAM kit delivers 512 GB across eight 64 GB DDR5 RDIMM modules. It is built for the Supermicro X14SRA-F motherboard and runs at 6400 MT/s with CL52 latency at 1.1 V. Registered ECC and 4Rx4 organisation let the memory controller address every slot at full rated capacity.

Registered ECC architecture and population rules

Registered buffering reduces electrical load on the memory controller so all eight slots can be populated simultaneously. ECC corrects single-bit errors in flight to prevent silent data corruption. The kit matches the board’s 288-pin RDIMM requirement and its specific population order; consult the motherboard manual for the exact installation sequence before fitting.

Suited for capacity-bound server workloads

This kit suits administrators who need the maximum validated density on a Supermicro X14SRA-F platform. It is not for systems that accept only unbuffered UDIMMs or SODIMMs, nor for boards that do not support 4Rx4 registered modules at this speed. Buyers requiring lower capacities or different form factors should select a matching alternative.

Questions about this item

What is the first limit you hit when running the 512GB 8x64GB DDR5 6400 CL52 kit at full capacity on a Supermicro X14SRA-F?

The memory controller must support 4Rx4 registered DIMMs at DDR5 6400 with 1.1V to recognise all 512GB and run at the rated speed.

How do the 1.1V registered ECC modules behave for heat and fan noise during continuous operation?

Registered architecture offloads the memory controller so every slot runs fully populated, while ECC corrects single-bit errors on the fly.

What motherboard and population rules must already be in place for this 288-pin RDIMM kit to work?

A Supermicro X14SRA-F motherboard with DDR5 6400 support and the correct DIMM population order from the system manual.
